[0046] See also Figure 1-4 The embodiment of the present invention discloses a water quality monitoring system 100, including a main control system 10, a protective tube 20, a sensor 30, a float mechanism 40, a power supply device 50 and a communication device 60. The protective tube 20 has a through hole 21; the float mechanism 40 can float and be built into the through hole 21; the sensor 30 is installed on the float mechanism 40 and can float up and down in the through hole 21 of the protective tube 20 with the float mechanism 40. The sensor 30, the power supply device 50 and the communication device 60 are all electrically connected to the main control system 10. When in use, the protective tube 20 is vertically installed on the shore 200 of a water-related area such as a river, lake or sea. The water to be monitored enters the protective tube 20, and the sensor 30 detects the water entering the protective tube 20 to obtain water quality information of the water area. The power supply device 50 is used to provide the power required for the operation of the water quality monitoring system 100, and the communication device 60 is used to send the water quality information detected by the sensor 30 to a remote terminal to facilitate monitoring, management, early warning and scientific research by relevant departments.

[0047] The water quality monitoring system 100 disclosed in this embodiment provides a protective tube 20, installs the sensor 40 on the float mechanism 40, and floats the float mechanism 40 inside the protective tube 20. The protective tube 20 can protect the sensor 30 and the float mechanism 40. Even in bad weather, the sensor 30 can work normally and provide real-time and effective data.

[0048] Communication device 60 utilizes BeiDou short messages and 4G communications to transmit data and enable remote monitoring, with BeiDou as the primary communication method and 4G as a supplementary method to ensure data transmission quality. Sensor 30 can be used to detect, but is not limited to, one or more of the following: temperature, salinity, conductivity, pH, nutrients, color, turbidity, and chlorophyll in the water to be monitored.

[0049] In some optional embodiments, the float mechanism 40 includes a float 41, a first fixed plate 42, and a claw 43. The first fixed plate 42 is built into the through hole 21; the bottom end of the claw 43 is connected to the first fixed plate 42, and the claw 43 and the first fixed plate 41 enclose a receiving groove; the float 41 is installed in the receiving groove; and the sensor 30 is installed at the bottom of the first fixed plate 42.

[0050] In some optional embodiments, the number of the claws 43 is four, and the four claws 43 form a group of two, and the two groups of claws 43 are arranged in a cross shape.

[0051] It is understood that the float mechanism 40 is not limited to using claws 43 to secure the float body 41. Bolt fastening or clip fastening can also be used to secure the float body 41, depending on the actual design requirements. It is also understood that the number of claws 43 is not limited to four, and can be set to three or more, depending on the actual design requirements.

[0052] The float 41 is made of foam material. Of course, the float 41 can also be made of other materials according to changes in the detection environment, such as plastic or stainless steel.

[0053] In some optional embodiments, the float mechanism 40 further includes a second fixed plate 44 and a connecting rod 45. The second fixed plate 44 is located on a side of the first fixed plate 42 away from the float body 41. The second fixed plate 44 has a latch 441, into which the sensor 30 is latched. One end of the connecting rod 45 is connected to the first fixed plate 42, and the other end is connected to the second fixed plate 44. The connecting rod 45 is used to further secure the sensor 30, preventing it from falling off the first fixed plate 42 and affecting the operation of the device.

[0054] In some optional embodiments, there are two connecting rods 45, which are respectively provided on both sides of the sensor 30. Of course, the number of connecting rods 45 is not limited to two, and can also be one or more than two, depending on actual design requirements.

[0055] In some optional embodiments, the second fixed plate 44 includes a first plate body 442 and a second plate body 443 detachably connected to the first plate body 442. The first plate body 442 has a first notch on the side facing the second plate body 443, and the second plate body 443 has a second notch on the side facing the first plate body 442. When the first plate body 442 and the second plate body 443 are assembled, the first notch and the second notch together form the bayonet 441, and the middle portion of the sensor 30 is secured to the bayonet 441. Preferably, the first plate body 442 and the second plate body 443 are detachably connected by bolts. During assembly, the first notch and the second notch are aligned with the sensor 30, and the first plate body 442 and the second plate body 443 are assembled from both sides of the sensor 30, and then fastened with bolts. This design greatly facilitates installation of the second fixed plate 44.

[0056] In some optional embodiments, the water quality monitoring system 100 further includes a cable 70 for electrically connecting the sensor 30 to the main control system 10. A first threading hole 411 is formed through the float body 41, through which one end of the cable 70 passes and is connected to the sensor 30. The provision of the first threading hole 411 simplifies the connection of the cable 70 and prevents the cable 70 from becoming entangled in the float mechanism 40 and affecting the upward and downward movement of the float mechanism 40.

[0057] In some optional embodiments, the end of the cable 70 near the float 41 is configured as a spiral cable 71. The spiral cable 71 can buffer the float 41 when it floats up and down, preventing the cable 70 from being pulled by the external force of the float 41 when the float 41 floats up and down, resulting in poor contact between the cable 70 and the sensor 30.

[0058] In some optional embodiments, the protection tube 20 is provided with a plurality of water inlets 22 along the radial direction. The provision of the water inlets 22 can ensure that the liquid inside the protection tube 20 and the liquid outside the tube are exchanged normally, thereby improving the detection accuracy.

[0059] In some optional embodiments, the water inlets 22 are divided into two groups, each group of water inlets is arranged in a straight line along the axial direction of the protection tube 20, and the two groups of water inlets 22 are arranged in a cross shape.

[0060] In some optional embodiments, an anti-corrosion layer is coated on the inner and outer surfaces of the protection tube 20. The anti-corrosion layer can prevent organisms from adhering to the inner and outer walls of the protection tube 20 and affecting the measurement results.

[0061] In some optional embodiments, the water quality monitoring system 100 further includes a cover plate 80 for sealing the top of the protective tube 20. The cover plate 80 has a second threading hole 81 formed therethrough for passing the cable 70 therethrough. The cable 70 is passed through the second threading hole 81. The cover plate 80 prevents external components from falling from the open top of the protective tube 20 into the through hole 21 of the protective tube 20 and affecting the raising and lowering of the float mechanism 40.

[0062] In some optional embodiments, the water quality monitoring system 100 further includes a support frame fixedly installed in the through hole 21 to prevent the float mechanism 40 from falling out from the bottom of the protective tube 20, thereby avoiding loss of the float mechanism 40 and the sensor 30.

[0063] In some optional embodiments, the support frame includes two support rods arranged in a cross shape.

[0064] In some optional embodiments, the protective tube 20 includes a first tube body 23, a second tube body 24, and a third tube body 25. The first tube body 23 is made of a transparent material, one end of the second tube body 24 is connected to the top end of the first tube body 23, and one end of the third tube body 25 is connected to the bottom end of the first tube body 23. By making the first tube body 23 of a transparent material, an operator can observe the interior of the protective tube 20 through the first tube body 23 without disassembling the protective tube 20. The water inlet 22 is located in the third tube body 25.

[0065] It is understandable that in order to facilitate observation of the float mechanism 40 , when the protection tube 20 is installed on the shore base 200 , the liquid level should just penetrate to the first tube body 23 , so that the float mechanism 40 can just float to the first tube body 23 .

[0066] In some optional embodiments, the water quality monitoring system 100 further includes a solar panel 90 for supplying power to the power supply device 50 , and the solar panel 90 is electrically connected to the main control system 10 .

[0067] In some optional embodiments, water quality monitoring system 100 further includes a support column 101 and a solar mount 102. Support column 101 is intended for installation on the shore, solar mount 102 is mounted on top of support column 101, and solar panel 90 is mounted on solar mount 102. Power supply 50 is also mounted on support column 101 and includes a cabinet 51 and a lithium battery assembly mounted within cabinet 51. Preferably, main control system 10 may also be built into cabinet 51.

[0068] In some optional embodiments, the water quality monitoring system 100 further includes a lightning rod 103 , which is installed on the top of the solar support 102 .
